The web then passes through a second treatment station where sterilizing liquid is sprayed as a fine mist onto a heated surface which vaporizes the sterilizing liquid. The vapor condenses on the passing web to further sterilize the web. One or more heaters again vaporizes the sterilizing agent which is on the packing web to remove the sterilizing agent. The sterilized packing material web is then cut into individual package units after the web has been filled with sterile contents. | |
